Abstract: A hinge is provided. The hinge includes a first plate, a second plate, a third plate, a shaft, a first elastic element, and a second elastic element. The second plate is connected to the first plate. The third plate is disposed on the second plate. The shaft is connected to the first plate and the second plate. The first elastic element surrounds the shaft. The second elastic element is connected to the second plate and the third plate. The second plate is rotatable around the shaft via the first elastic element. The second plate is movable relative to the third plate via the second elastic element.

Abstract: A portable data storage device includes at least one component that generates heat, an enclosure wall made of a first material and having a thermal conductivity and an exterior layer. The enclosure wall surrounds the at least one computer component and includes outer and inner boundaries. The exterior layer is made of a second material and has a thermal conductivity that is less than the thermal conductivity of the first material. The exterior layer is covers the outer boundary of the enclosure wall and includes an outer surface and an inner boundary. The outer boundary of the enclosure wall interfaces with the inner boundary of the exterior layer so that the outer surface of the exterior layer is in direct contact with the environment and the outer boundary of the enclosure wall is not. Heat is transferred to the environment at the outer surface of the exterior layer.

Abstract: A voting device includes a touch panel and a rechargeable battery, the voting device being part of a voting system. The touch panel is configured to display a topic under discussion and options relating thereto. The touch panel is also configured to output data as to vote or option chosen by a voter through a wireless network, together with barcode data identifying the voter. The rechargeable battery supplies power to the voting device. A voting system using the voting device and allowing instant calculation and display of the voting result is also provided.

Abstract: A wireless positioning tracker includes a communication unit, a function setting unit, a position tracking unit, and an alarm unit. The communication unit can communicate with external communication devices by human voice or by message. The function setting unit receives function commands from the external communication devices, for setting the wireless positioning tracker. The position tracking unit captures a current longitude and latitude of the wireless positioning tracker through a global positioning system unit for obtaining the current position. The past track of a moving object can be stored. The alarm unit can call for help from contact entities when the moving object presses a single alarm keystroke. The moving object may be monitored, tracked, and positioned by contact entities at all times.
